ALCORN RECTOR, OF NEW YORK, N. Y.

. INVERTED INCANDESCENT LAMP OR GAS-BURNER.

To aZZ whom, it may cmwcrn:

Be it known that I, ALooRN REo'roR, a citizen of the United States, residing at New York, in the county of New York and State of New York, have invented new and useful Improve- .miX with the gas as it passes the point of the regulating needle-valve and of means for increasing and intensifying the light, while at the same time it reduces the consumption of gas, as illustrated in the accompanying drawings and described in the following specification and claims.

surface of the regulating needle-valve is also provided with a thread 4. Fitting around said needle-valve is a guide-tube 5, having an internal thread 5, which meshes with'the external thread 4 of said needle-valve- Secured to the lower endof said guide-tube .5 and integral therewith is a cylindrical cup 6, provided in its bottom with a perforation 7 so that when said cup is turned to the right it ascends by means of said mentioned threads and forces the point of the needle-valve into said perforation 7, and when said cup is turned to the left it descends, withdrawing said point from said perforation. The flow of the gas is thus regulated at will. A mixing-tube 8 has its upper end securely threaded to said cup, so that when said mixingtube is revolved it carries with it said cup and causes it to rise or fall, as before described. Securedto the lower end of said mixing-tube .is a burner-head 9, and projecting from said burner-head is a circular extension or protecting flange 10. The purpose of this flange is to keep the burner-head and mixing tube from getting too hot, because if they get beyond acertain temperature it changes the mixture of gas and air, rnaking combustion imperfect. Imperfect combustion causes soot to form on the burner-head. This is prevented by the flange, because it forces the flame through the mesh of the mantle, brightening it'and preventing the flame from coming in direct contact with the burner-head and mixing-tube, keeping them moderately cool. The mantle 18 is held in the center of the draft or intensifying tube 14 and at the proper heightpn the burner-head 9 by means of a band 19. The circular extension or protecting flange 10 holds the mantle in the center of the draft-tube 14. The handles 21, fitting in and meshing with bayonet-slots 1& located at the extreme lower end of the draft-tube 14,

hold the mantle at the proper height. The

lower end of the burner-head is provided with a perforated-bottom 11. Thepurpose of this perforated bottom is to hold the flame at this point and prevent it from flashing back into The bottom 11, as shown in Fig. 10, has a star-shaped opening, which performs the same service as the bottom 11, (shown in Fig. 3,) and I have found in my ex periments that this last-mentioned bottom 11 causes the flame to project a greater distance from the burner head than the bottom 11 and, indeed, at a greater distance than any other bottom I have been ableto use. Diflersecured the upper end of said mantle. Said ent shaped glassware used in connection with band is provided with two handles 21. The

my invention causes different drafts to pass through the lamp, making it preferable to use the different kinds of bottoms. Said mixingtube 8 is provided with three or more perforations 12, and extending from each one of these perforations outwardly is an air-tube 13. Surrounding said guide-tube 5, mixing-tube 8, burner-head 9, and protecting-flange 10 is a draft or intensifying tube 14:, provided at its upper end with perforations 16' and at its lower end with an upper shoulder 14: and a lower shoulder 14 This draft or intensifying tube is also provided with circular perforations 15, which register with the perforations 12 in the mixing-tube, and the outer ends of the air-tubes 13 pass through said perforations 15 and are secured therein. Said draft or intensifying tube extends upward to the top of the guide-tube 5 and is secured thereto, so that when said draft-tube is revolved the said mixing-tube is also revolved, thereby regulating the lamp and controlling the consumption of gas. The upper end or head 16 of the draft or intensifying tube is provided with slot-perforations 16 for the escape of heat generated by the flame below.

It will be observed that the air enters the mixing-chamber immediately below the point of the needle-valve and mixing with the gas produces a thorough combination before it passes through the bottom of the burner-head. In all other inverted lamps that have come under my observation air is introduced into the mixing-chamber above the point where the heat passes from the upper framework of the lamp and mixes with the gas. Hot air from the flame is detrimental to the combustionof the gas by the lamp, as it causes soot to collect upon the burner-head. While hot air from the flame is injurious, warm air mixes more readily with gas, forming a better compound.

It will be observed that while the air enters the perforations 15 through the air-tubes 13 into the mixing-tube 8 the heat passes up from the burner-head through the draft or intensifying tube, warming the mixing-tube and the hot-air tubes 13, and thus warms the air as it passes through said air-tubes. The hot air from the flame passes up through the raft or intensifying tube and out of the openings in the head 16, and by no possibility can the hot air from the flame mix with the gas en route to the burner-head. The top of the draft or intensifying tube is closed, and the openings are around its circumference. The purpose of this is to spread the heat, and thereby keep it from burning anything immediately over the lamp.

The lower end of the draft or intensifying tube 14 is provided with two bayonet-slots 14 The band 19 is provided near its lower ,end'with an annular groove 20, in-which is said band is pushed up into the lower end of said draft or intensifying tube, and the handles 21 are turned into said bayonet-slots. These handles are used to manipulate the mantle and to stop said band 19 at the proper place, so that the said handles can be turned into the bayonet-slots 14?.

Extending from the surface of the draft or intensifying tube near its lower end and resting on shoulder 14 is a band 25, enlarged at its lower end, which enlargement forms the bulb-holder 25. A bulb 26 is secured to said bulb-holder in any practical way. Said bulb is preferably made of opal glass, which gives an electric effect to the light. Sometimes instead of using a bulb 26 I use a short glass tube 27, which is secured to the same bulbholder justdescribed. A short distance above said bulb-holder 25 and fitting around said draft or intensifying tube is another band 30. Extending from said band 30 outwardly and downwardly is a globe-holder 31, provided with three screws which hold a globe. In said globe-holder is secured a globe 34, as shown in Fig. 1, or a globe 35, as shown in Fig. 7, or a shade 36, as shown in Fig. 8. Any other style of globe or shade applicable to this kind of lamp may be used.

My lamp is so constructed that I may use with it globes open or closed at the bottom. When using a closed globe, as shown in Fig. 7, I provide the globe-holder with air-inlets 31, as shown in Fig. 7, and use a short glass tube 27 in connection with the closed globe, in which case the cold air passes down over the top of the globe, through said air-inlets 31 to the bottom end of the tube 27, and then up through the draft or intensifying tube, as indicated by arrows.

The superior advantages of my lamp over all others may be summed up as follows: From its construction it allows the use of glassware open or closed at the bottom.

My draft or intensifying tube increases the brilliancy of the light by causing the gas, air, and flame to move more rapidly, rendering the heat units greater than in other lamps. The heat passes out at the top of the draft or intensifying tube. The air to be mixed with the gas is taken in through the lateral tubes below this point, rendering it impossible for the direct heat of flame to affect combustion.

In all other invert-ed lamps that have come under my observation, the heat generated by the flame passes the point where the air is admitted to mix with the gas, effecting the combustion. The effect of the heat from the flame causes imperfect combustion of gas, producing soot and destroying the brilliancy of the light, because the oxygen has not been completely consumed.

My draft or intensifying tube serves two purposes: First, it creates a draft; second,

it heats the mixed air and gas, 'therebyincreasing the brill-ian'cy'of the light by'rendering combustion more rapid.

My regulating needle-valve and burner in the mantle enable me'to turn the gas-low without causing smoke; c By my method I carry the heated air up between the inner wall of' the draft or intensifying tube and the outer wall of the mixingtube, passing between and around the lateral air-tubes, thus heating the air before it enters the mixing-tube.

My draft or intensifying tube is larger at its lower end than at its top. This is to prevent the blaze from striking against the inner wall of the tube and burning it.
